Detailed Description
Helicobacter pylori infection is a common problem in pediatric practice, it's an important cause of gastrointestinal pathology in children and its acquisition is related with poor socioeconomic conditions. H.pylori is a spiral, microaerophilic, gram-negative bacterium with four to six unipolar sheathed flagella.The human stomach, especially the antrum, is the most common reservoir of this agent. American board of orthodontists antibody blood group and Lewis blood-group antigen might expose cases to H. pylori infection, the most likely mode of transmission is fecal-oral or oral-oral. H.pylori infection is predominantly acquired during early childhood .
The majority of children with are asymptomatic although a percentage of the infected children develop H. pylori associated diseases such as iron deficiency anemia, B12 deficiency, chronic thrombocytopenic purpura. It can manifest with burning pain in the stomach, nausea, loss of appetite, bloating, weight loss.
Previous studies showed that geographic area, age, race, educational level, sanitation, and socioeconomic status are among the factors that influence the prevalence of H. pylori infection . No gender differences were found in the prevalence of H. pylori infection, while it was much higher among white people.
The overall prevalence of H. pylori infection in Egyptian school children was 72.38%. There was no significant difference in the prevalence of infection between boys and girls (73.80% vs. 70.34% respectively, or in the independent effect of sex by age. Of school children living in Sohag, 96.7% tested positive for H. pylori, compared with 81.3% of children from Giza and 61.9% from Cairo. Prevalence was also highest among children of low socio-economic class and decreased gradually among children of medium to high socio-economic class.
In a previous study conducted by Hunt et al., the prevalence of H. pylori was reported to be 48% among 2-4-year-old children in Ethiopia, while in Nigeria and Mexico it was 82% and 43%, respectively, among 5-9-year-old children..
The endoscopic findings in order of decreasing frequency in the Pediatric group were nodularity (93.0%), mucosal swelling (32.6%), spotty redness (25.6%), diffuse redness (18.6%), atrophy (9.3%), enlarged fold (4.7%), depressive erosion (4.7%), foveolar-hyperplastic polyp (2.3%), patchy redness (2.3%), red streak (2.3%), and raised erosion (2.3%).
Invasive and non-invasive tests could be used for diagnosis, while the gold standard is a biopsy specimen of gastrointestinal tract.
Triple therapy is considered to be the standard treatment for children. Proton pump inhibitor combined with two antibiotics has been shown to be very effective in clearing H. pylori from the stomach, it is recommended to treat with amoxicillin, clarithromycin and a proton pump inhibitor for 2 weeks.
